    decrease in muscle mass and strength due to inactivity

    Muscle atrophy, also known as muscle wasting, refers to the decrease in muscle mass and strength due to a variety of factors such as prolonged inactivity, aging, malnutrition, or certain medical conditions like ALS or muscular dystrophy. This condition results from an imbalance between protein synthesis and degradation within muscle tissues, leading to the shrinkage and weakening of muscle fibers.
